Description

Technical Field

[0001] The present invention relates to a maintenance system, in particular to a maintenance system for a station computer interlocking system. Background Art

[0002] The station computer interlocking system is a critical component of railway operation safety. Its maintenance capabilities are directly related to its reliability. The interlocking system's maintenance station at the railway station records and analyzes the system's operational status, assisting on-site personnel in resolving system issues. It also sends station information to the monitoring system via the serial port. Currently, system maintenance stations are primarily single-station models, making it difficult to centrally maintain the computer interlocking systems at each station. On-site fault alarms make it difficult to notify on-site maintenance personnel or equipment manufacturers in real time. Furthermore, the maintenance station's remote diagnostic function still relies on traditional telephone line dial-up, resulting in weak communication capabilities and poor channel quality. Consequently, centralized maintenance and remote diagnostic functions are not fully utilized. Summary of the Invention

[0027] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operating process. Obviously, the described embodiment is only an embodiment of a part of the present invention, not all embodiments, and the protection scope of the present invention is not limited to the following embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0028] "One embodiment" or "embodiment" referred to herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. In the description of the present invention, it should be understood that the terms "first", "second" and "third" in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units that are inherent to these processes, methods, products or devices.

[0029] The computer interlocking system consists of six subsystems: man-machine interface (MMI), interlocking processing (IPS), gatekeeper console (GPC), diagnostic maintenance (SDM), redundant network (RNET) and power supply (PWR). The SDM device is the electrical maintenance terminal of the station computer interlocking equipment and is responsible for the maintenance of the station computer interlocking system. Traditional remote maintenance solutions such as Figure 1SDM equipment uses a modem to interface with the manufacturer's remote maintenance equipment to transmit maintenance and diagnostic information about on-site equipment. These devices are typically single-station devices, making centralized maintenance and management inconvenient. On-site fault alarms are difficult to notify on-site maintenance personnel or equipment manufacturers in real time. Furthermore, traditional dial-up telephone lines offer weak communication capabilities and poor channel quality, hindering the effective implementation of centralized maintenance and remote diagnostic functions. This present invention, based on actual on-site conditions, designs an optimized solution for centralized maintenance and remote diagnostics in computer interlocking systems, enabling the provision of higher-quality services to users.

[0030] A station computer interlocking system maintenance system, such as Figure 2 As shown, it includes SDM equipment and DCE equipment. The SDM equipment is connected to the computer interlocking system, and the DCE equipment is connected to the SDM equipment. Multiple communication interfaces or communication modules are reserved on the DCE equipment.

[0031] The present invention adopts DCE (data transmission relay) equipment to replace the traditional modem. Meanwhile, the DCE equipment is also a key equipment for information isolation and can communicate with the SDM equipment in one direction or two directions according to the networking situation.

[0032] The maintenance system also includes a centralized user maintenance system (UCM) that communicates with the DCE equipment at each station and includes both a server and user terminals. The UCM interfaces with the DCE equipment via the network and is capable of connecting to at least 30 stations. The UCM is responsible for centralized equipment maintenance and can upload relevant information to the server via the network.

[0033] The maintenance system also includes a remote diagnostic center, which communicates with each station's DCE equipment and the user's centralized maintenance system. This center monitors the operating status of equipment across the network, reanalyzes cloud data, automatically transmits equipment alarm status to maintenance technicians, and provides technical support for on-site maintenance. As a centralized monitoring system, the remote diagnostic center monitors alarm information from stations nationwide. It interfaces with existing CRM systems (customer relationship management systems) and can push information to user terminals, including text messages, images, audio, and video.

[0034] The maintenance system also includes a cloud diagnostic data service center, which communicates with the DCE equipment at each station, the remote diagnostic center and the user's centralized maintenance system, and is responsible for storing, analyzing and organizing the collected log data.

[0035] The DCE equipment reserves the communication function with MMI (computer interlocking operation display device) and IPS (interlocking computer). The interface adopts RS485 interface mode. To ensure information security, the information adopts one-way serial port transmission protocol.

[0036] The communication interfaces reserved for DCE equipment include interfaces for communicating with the display device and interlocking processing computer of the computer interlocking system. The interfaces adopt RS485 interface mode. To ensure information security, information adopts one-way serial port transmission protocol.

[0037] The DCE device has a USB interface that can store log files sent by the SDM device under the control instructions of the SDM device. The DCE device supports USB flash drives of no less than 32GB. The DCE device has a WIFI module that can access the WIFI network provided by the user and is responsible for real-time transmission of relevant information of serial ports 1 / 2 according to the SDM device configuration or control instructions. The DCE device has an LTE module that can access the mobile network and communicate with the cloud server, responsible for real-time transmission of alarm information and information customized by the SDM device. Alarm classification or customized information can be sent by the maintenance center or the SDM device. The DCE device has two RJ45 network interfaces, one of which is responsible for transmitting information from serial port 1 and interfacing with the centralized maintenance system. One network port is responsible for transmitting files sent by the SDM device and can be interfaced with the centralized maintenance interface or the user's laptop.

[0038] The DCE device receives real-time information from the SDM device via serial port 1, such as station information, operational information, and real-time alarm information. It receives system log files from the SDM device via serial port 2, and the SDM device sends control commands and configuration information to the DCE device. Control commands include turning Wi-Fi / LTE on and off, rebooting the DCE device, and so on. Configuration information includes IP address information and alarm classification information. To support limited remote control of the SDM device, a remote control function is designed. However, given the inherent risks of this function, it is user-selectable and can be enabled or disabled. To use this function, the user sends control commands to the SDM device via serial port 3 from the DCE device. Upon receiving the control commands, the SDM device executes the corresponding function using a local script (customized by the user). To further increase security, the DCE device sends a local script verification code when sending a control command to the SDM device. The control command must be sent together with the local control script verification code. The SDM device receives the control command and local script verification code sent by the DCE device. When the control command and the local script verification code are verified, the SDM device refers to the local script execution function corresponding to the control command.

[0039] The SDM device also collects device and operational information from the computer interlocking system's display devices and interlocking processing computers. The SDM device collects information from various systems within the system and transmits it to the DCE device via a serial port. The information collected by the SDM device includes not only the aforementioned real-time information and log information related to station operations, but also information about the computer interlocking system itself, such as the CPU, memory, and hard disk usage of the interlocking processing computer (IPS), as well as software and hardware versions, useful for maintenance. The SDM device is capable of directly interfacing with a laptop via a serial port to transmit log files. The SDM device collects MMI-related hardware information and log file information through a watchdog program installed in the MMI display device of the computer interlocking system. The collected information is transmitted by a program installed in the SDM device. For subsequent stations, the watchdog program can be integrated into the SDM device software after mature implementation. The SDM device executes predefined operational scripts through the watchdog program, which, in conjunction with the watchdog program in the MMI, enables automatic software deployment.

[0040] When applying this system, the system can provide different levels of services according to different system networking conditions and user needs.

[0041] ① Deploy only DCE devices

[0042] The site has the ability to copy data via USB or laptop, or the user can temporarily provide a WIFI network, and the system will automatically upload it to the cloud service.

[0043] ②Deployed DCE equipment and centralized user maintenance

[0044] It has the ability to centrally maintain the system. Relevant log files can be copied directly from the user's service center, and the user maintenance center can be connected to the cloud service.

[0045] ③Deploy DCE equipment + cloud services

[0046] Users can directly have the ability to perform centralized maintenance through the Internet, and our company can provide timely push of fault information and higher-quality remote maintenance technical support. The application scenarios of this application are as follows:

[0047] Application scenario examples

[0048] (1) Interlocking machine driver board failure, single system restart

[0049] After collecting the information, the SDM sends it to the DCE via the serial port. The DCE identifies it as critical based on the information category and transmits it to the cloud service via the mobile network (LTE). The system automatically notifies the technical support engineer of the problem and schedules a replacement for the board. If the user is unclear about the replacement process, the system can push a video of the replacement to their mobile phone. The maintenance system compiles station hardware failure information based on the station information and prepares the stock for on-site delivery.

[0050] (2) The interlocking system network is blocked and the operating machine loses its display

[0051] Before the problem occurred, the SDM detected abnormal operation of the MMI network card and notified the user through the centralized maintenance system for prompt repair. The user did not pay attention to the information. After the problem occurred, the user requested an analysis of the problem. The user maintenance personnel clicked "Collect Logs" at the system maintenance station. The SDM aggregated the system information and logs of each operating machine.

[0052] The user chooses to save to a USB disk;

[0053] The user inserts the USB into the DCE and copies the log to the USB storage on the SDM, completing the log copy. The user then sends the log to our company via his or her own computer.

[0054] Or the user has connected DCE to the public network. The user clicks on SDM and sends it to the manufacturer. DCE transmits the logs collected by SDM to our company's log server;

[0055] (3) The on-site interlocking machine switches asynchronously, the entire station is blocked, and the on-site operator calls for support through the smart terminal.

[0056] SDM transmits real-time on-site information to the company's centralized maintenance system. The system automatically generates relevant operation videos and pushes them to the user's mobile phone. The on-site operator completes the relevant operations within 3 minutes according to the prompts.

[0057] (4) The site needs to evaluate the condition of the on-site equipment and customize the maintenance plan for the new year;

[0058] The system collects operational information from each device and performs trend analysis on it. Information such as the CPU and memory usage of industrial computers, the percentage of damaged boards, the age of the equipment, and the system power supply voltage are also collected and analyzed. This provides a basis for our company to develop preventive maintenance plans.

[0059] (5) User-customized training plan

[0060] The system regularly collects user operations, including those performed by on-site operators and electrical maintenance personnel, and provides recommended training content for less frequent operations. After user confirmation, the content is pushed to the smart terminal.

[0061] Compared with the prior art, the advantages of this application are as follows:

[0062] 1. Fast information transmission speed. The traditional interface has a transmission capacity of only 56KbPS, while the new interface has a transmission capacity of 1Mbps.

[0063] 2. Information security is controllable, and the use of multi-serial port customizable data transmission channels avoids potential security attacks from the network.

[0064] 3. The interface mode is flexible, and it uses common RJ45, USB, WIFI, LTE and other multi-mode channels to transmit system maintenance information. It is more flexible than the current system, and the related technology has mature applications in other fields.

[0065] 4. Customized user execution script service can customize local automated maintenance functions according to user needs, making it easier for users to expand and control.

[0066] 5. Centralized maintenance and remote diagnosis facilitate centralized maintenance management. On-site fault alarms can notify on-site maintenance personnel or equipment manufacturers in real time.

[0067] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the claims.
